I think my aquarium has finally driven me insane. It has been up and running for approximately 4 months. I still have a lot of things on my items to buy list including about 30 lbs of live rock. I only have 2 fish however there should be more.. There should be 4 in all but somehow 2 fish including 1 bicolor angel have simply completely disappeared!!! I have an open top on my aquarium and I have to wonder if they committed harry carry? Is this common among open top tanks? I do have 2 cats as well...... I Any thoughts???
